2. Solve for x. Round answer to the nearest tenth. *
slavikrds [6]

Answer:

x ≈ 7.4

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos22° = \frac{adjacent}{hypotenuse} = \frac{x}{8}

Multiply both sides by 8

8 × cos22° = x, thus

x ≈ 7.4 ( to the nearest tenth )

The mean length of 5 childrens' index finger is 5.6cm.
Brilliant_brown [7]

The mean length (rounded to 2 DP) of these 8 people's index finger is 5.83

<h3>What is the mean length (rounded to 2 DP) of these 8 people's index finger?</h3>

The given parameters are:

<u>Children</u>

Mean = 5.6 cm

Frequency = 5

<u>Adult</u>

Mean = 6.2 cm

Frequency = 3

The mean length of these 8 people's index finger is calculated as:

\bar x = \frac{\sum fx}{\sum f}

So, we have

Mean = (5.6 * 5 + 6.2 * 3)/(5 + 3)

Evaluate

Mean = 5.83

Hence, the mean length (rounded to 2 DP) of these 8 people's index finger is 5.83
